由于无法启动服务，无法卸载 postgresql 包？

Question

我只是不明白发生了什么。

sudo apt-get remove postgresql

结果是：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'postgresql' is not installed, so not removed

我的意思是，它为什么要尝试启动服务器。是的，我是一个 unix noob 和一个巨大的 postgres noob，所以请耐心等待，但是在我尝试卸载时随机启动服务器似乎很随机。只是不明白。

如何完全卸载 postgresql？

Answer 1

你的第一次安装是不确定的，这会破坏它：

sudo dpkg --purge postgresql-9.1

现在您可以重新安装软件包：

sudo apt-get -f install
sudo apt-get install postgresql-9.1
